When the heat and pressure hits the limestone, calcite seed crystals form. How is Marble Formed. This refers to the formation of metamorphic rocks under high pressure. These particles form layers of sand and pebbles that undergo compaction and cementation to create sandstone. Limestone, or calcium carbonate, is the common rock found throughout the world. Here it is transformed into calcium carbonate--limestone--where it can be safely stored as solid rock and help to combat climate change. It can also be used on roofs to prevent or reduce weather or heat related roof damage. The relationship of rock layers vertically and laterally is indicative of large-scale changes in the environment. With this process, water that is slightly acidic slowly wears away stone. When limestone is heated in a kiln, the calcium carbonate breaks down into calcium oxide and carbon dioxide. The extent to which the rocks are changed depends on: 1. Under gentler conditions that are still not completely understood, the calcite in limestone is altered to dolomite. If the limestone is pure, a white marble is formed. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.
